I just started using Nagios3 to monitor my networks and it looks like it will save a lot of trouble in future (if I can get detailed enough plugins, like check_psu_about_to_explode for instance ). Good thing NConf is here to help out with the configuration. Configuring Nagios3 without a configurator would have been a nightmare.

I do have a couple of usability issues ,but they would be offtopic for this subforum.
